Columbus, OH Weather

The city’s climate is humid continental transitional with the humid subtropical climate to the south characterized by warm, muggy summers and cold, dry winters. Columbus is within USDA hardiness zone 6a. Winter snowfall is relatively light, since the city is not in the typical path of strong winter lows, such as the Nor’easters that strike cities farther east. It is also too far south and west for lake-effect snow from Lake Erie to have much effect, although the lakes to the North contribute to long stretches of cloudy spells in winter.

The highest temperature recorded in Columbus was 106 °F (41 °C), which occurred twice during the Dust Bowl of the 1930s—once on July 21, 1934, and again on July 14, 1936. The lowest recorded temperature was −22 °F (−30 °C), occurring on January 19, 1994.

Columbus is subject to severe weather typical to the Midwestern United States. Severe thunderstorms can bring lightning, large hail and on rare occasion tornadoes, especially during the spring and sometimes through fall. A tornado that occurred on October 11, 2006 caused F2 damage. Floods, blizzards, and ice storms can also occur from time to time.
